5G Brooklyn Summit

Every spring, the best telecom engineers in the world come to meet their peers. Ted Rappaport, Andrea Goldsmith, Gerhard Fettweis, slews of CTOs, and many others will present. Do watch the IEEE Livestream. Ted and Gerhard will present the future, including terahertz. I'll be asking about:

Reach of mmWave/density of cells required. Who will do mmWave in the next 5 years?

Latency of 5G air interface. Now 8-12 ms in the field, will it come down to the 1-4 ms in the lab?

Edge Clouds where? Tower, local in C-RAN or exchange, further back and slower?

How to simplify standards to bring down cost and time to market?

Who, what, where, when, and how?

Samsung has delivered 5G chip samples to BBK's Oppo and Vivo, the #2 or #3 phones manufacturer. Samsung is facing off against Qualcomm in the 5G market. Qualcomm is unfazed and reportedly moving the production of their next chip from TSMC to Samsung. 

Sprint's 2.5 GHz 5G is delivering 100-500 megabit downloads consistently. That bodes well for China Mobile, using the same frequencies.

Vodafone, BT, and soon 3UK are delivering modestly sized 5G mid-band networks. Vodafone is also live in Spain and Italy. 

Sunrise in Switzerland is using 5G mid-band for fixed wireless in rural areas.

Welcome  1,000,000 Koreans bought 5G in the first ten weeks. The demand is there, and most of the technology works. Meanwhile, the hype is unreal. Time for reporting closer to the truth.

The estimates you hear about 5G costs are wildly exaggerated. Verizon is building the most advanced wireless network while reducing capex. Deutsche Telekom and Orange/France Telecom also confirm they won't raise capex.

Massive MIMO in either 4G or "5G" can increase capacity 3X to 7X, including putting 2.3 GHz to 4.2 GHz to use. Carrier Aggregation, 256 QAM, and other tools double and triple that. Verizon sees cost/bit dropping 40% per year.

Cisco & others see traffic growth slowing to 30%/year or less.  I infer overcapacity almost everywhere.  

Believe it or not, 80+% of 5G (mid-band) for several years will be slower than good 4G, which is more developed.
